TROUSERS-KNEE-LIFTING DEVICE.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed June 18, 1914. Serial No. 845,819.

To all whom it may concern Be it known that 1, Solomon ABRAMSON, acitizen of the United States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and Improved Trousers-Knee-Lifting Device, of which the followingis a full, clear, and exact description.

This invention relates to a lifting device for each leg of a pair oftrousers for the purpose of automatically lifting the lower portions ofthe legs when the knees are bent, as in sitting down, ascending steps,stooping and the like, whereby the objectionable bagging of the trouserslegs at the knees is positively prevented and movement of the legs isunimpeded.

The general objects of the invention are to provide an extremely simpleand effectlve lifting device applied inside the legs of a pair oftrousers at the knee portions, which serve to automatically exert alifting action when the knee is bent, as above described, the liftingdevice or attachment comprising essentially a V-shaped fabric structurewhich has its vertex placed directly at the knee portion of the trousersleg with the two members of the device extending upwardly therefrom tothe lateral portions of the trousers leg where the extremities of themembers are secured to the inside and outside seam or adjacent theretoat points between the level of the knee and the level of the crotch, thesaid members being preferably free from the trousers at pointsintermediate the knee and the side seams, so that when the knee is bentthese oppositely-extending obliquely disposed members produce an upwardpull on the trousers leg from the knee portion to the bottom, wherebythe bagging at the knees of the trousers legs is prevented without thenecess ty of the wearer pulling up the trousers legs,'as is now commonlythe case, and also without the free movement of the legs beinginterfered with.

The lifting attachment is preferably made of some smooth fabric, such assilk, so that the low co-efiicient or friction between it and the kneeof the wearers leg will enable the crotch portion of the attachment toslide along the knee when the leg is bent.

For a more complete understanding of the invention reference is to behad to the following description and appended claims aken in connectionwith the accompanying drawing, in which similar characters of referenceindicate corresponding parts in all the views, and in which- Figure 1 isa view of the lower portion of a person wearing a pair of trousersequipped with the knee lifter attachments, one of the legs being shownraised to illustrate the action of the trousers knee lifter; Fig. 2 is aside view showing the person in a sitting posture, the trousers beingshown broken away and in section to illustrate the position and actionof the trousers knee lifter; Fig. 3 is a side view showing the trouserslegs before the person takes the sitting posture shown in Fig. 2; Fig ais a view of a pair of trousers turned inside out to show the positionof the knee lifters and the manner of attachment thereof to thetrousers; Fig. 5 is a plan view of one of the lifting devices beforebeing applied to the trousers.

Referring to the drawings, 1 designates the legs of an ordinary pair oftrousers to which are applied the lifting devices 2, which are in thenature of attachments that are applied to the respective legs for thepurpose of causing the automatic lifting of the trousers legs at theknees when the wearer bends the legs, as in sitting down, stooping,stepping upwardly or ascending stairs. Each attachment comprises a pairof angularly disposed members 3 and f arranged in the form of a V andpreferably integrally connected at the crotch or vertex portion 5. Theattachment or lifting device is arranged within the trousers leg, andhence is concealed from view, and the position is such that the members3 and 4 extend upwardly from the knee portion 6 of each trousers leg tothe outer and inner side seams 7 and 8 of the trousers legs, thecxtremities 5' and a being secured adjacent the side scams 7 and S bybeing suitably stitched, as indicated at 9, Fig. 4-. The crotch orvertex portion of the f-shaped lifting device is stitched at 10 and 11to the knee portion of the trousers leg, so that the members 3 and i arepractically free at all points from the garment.

It will be noted that the points where the upper extremities of themembers 3 and 4,- are attached to the garment are located be tween thelevel of the knee and the level of the crotch 12 of the trousers, saidpoints being nearer the crotch than the knee portions of the trouserslegs. t will also be noted that the lifting attachments are carriedwholly by the front pieces of the trousers legs, as the members 3 and atdo not pass the inner and outer seams 7 and 8.

If desired, each lifting device may be pro- 1 vided with a strip -likeextension at 13 which is adapted to be folded at 1 1 so as to extendvertically between the members 3 and i when the device is applied to thetrousers, and this strip-like extension 13 is fastened by stitches 15 toeach trousers leg in a central position or coincident with the crease 16extending down the front of the trousers leg.

The lifting attachment is preferably made of some suitable fabric whichis comparatively smooth so that it will slide freely on the knee cap.

As shown in Fig. 3, and by the right leg in Fig. 1, the crotch portionsof the lifting devices are directly in front of the knee caps, so thatwhen the wearer bends the legs the crotches 5 will slide upwardly on theknee caps, as the members 3 and 4: exert a lifting action on the lowerportions of the trousers legs. In actual practice a device constructedas shown produces a lifting action of from four to five inches entirelyautomatically, so that the wearer does not have to pay any attention tolifting of the trousers legs as is now customary, for the purpose ofcomfort and for preventing bagging at the knees and the removal of thecreases.

From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of operation willbe readily understood by those skilled in the art to which the inventionappertains, and while I have described the device which I now considerto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such changes may bemade when desired as are within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A pair of trousers and leg-lifting devices fastened in the legsthereof, each device comprising a pair of members extending upwardly andoutwardly in opposite directions from the knee portion of the trousersleg to the inner and outer lateral portions, the upper and lowerextremities of the members being secured to the trousers while theintermediate portions of the 1nembers are free.

2. A. pair of trousers having a lifting device in each leg, whereby theportion of a leg from the knee down is automatically lifted when thewearers leg is bent at the knee, the lifting device comprising a pair ofmembers having their lower ends fastened to the knee portion of thetrousers leg and extending divergently-upwardly and having their upperends attached to the trousers leg adjacent the inner and outer seams andat points between the knee and crotch of the trousers.

3. A pair of trousers, a leg lifting device fastened to the front pieceof each leg of the trousers and embodying a flexible V-shaped structurefastened at its vertex to the knee portion of a. trousers leg andhavingits members extending upwardly, with the extremities of themembers fastened to the inner and outer lateral portions of the trousersleg.

1. A pair of trousers, a lifting device arranged in each leg andextending from the knee upwardly, said device being attached to thefront piece of the trousers leg and consisting of a pair ofupwardly-divergent tape-like members fastened at their lower ends to theknee portion of the trousers leg and extending therefrom to the innerand outer lateral portions of the trousers leg and attached thereto.

5. A trousers leg lifting attachment comprising a pair of tape-likemembers having their lower ends united in the form of a V and made offlexible material, said members being flat in a common plane.

6. A trousers leg lifting attachment comprislng a pair of members united1n the form of a V and provided with acentral tape-like extensionadapted to be folded to In testimony whereof I have signedmy name tothis specification in the presence of two subscribing witnesses.
